How to use the exp key

I think it is case of mistaken identity. There is a function called the power function. The general form of it is a*(b)^x or a times (b) to the power of x. a is just a constant factor (not equal to 0) and b is the so-called base ( also different from zero). Personnally I call this function the power function, but you find it is often called the exponential function.
The exponential function e^x is similar to the power function. The main difference is that its base is a certain irrational number called e (=2.718281828...).
What you want to do, as far as I can guess is to calculate 2000*(1+0.12)^20.
Simplify your life and set 1+0.12 as 1.12, and type in 2000 [*]1.12^20=
1.12^20=9.646293093. Multiplied by 2000, this gives you a final result 19 292.58
To enter the the power use the key marked as [X^y], [Y^x] or [^]

I am doing dB conversions and I do not know how to enter 10 61/20 as ten to this power

You can't enter it as such, but you can calculate the value as 1 0 y^x ( 6 1 / 2 0 ) =
"y^x" is the key just above the divide key. The parentheses keys are just above the 8 and 9 keys.

How do I use this calculator to find the x and y intercepts when the problem has both the x and y letters. it will not allow me to enter the full equation. example problem is 2x-5y=20 and I need to find...

x-intercept (or zero of the function)
Set y=0 in the equation and solve fo x: 2x-5(0)=20 and x=20/2=10

y-intercept (initial value)
Set x= 0 in the equation and solve for y: 2(0)-5y=20 and y=20/(-5)=-4

If the equation is in the slope-intercept form y=ax+b
1. y-intercept is b
2. To get the x-intercept ( zero of the function) Set y=0=ax+b, and x=-b/a

TI-84 Plus Silver Edition. When dividing negative powers of ten by other negative powers of 10 the calculator it just adds the the negative powers together. How do i fix this? An example: 5*10^-10 /...

To enter an exponent, positive or negative, use the EE (Enter Exponent) key (the shifted function of the , key just above the 7 key). Do 5 2ND [EE] (-) 1 0 / 5 2ND [EE] (-) 1 0 ENTER and you'll see 1.

What I think you're doing (I can't be sure without seeing your keystrokes) is calculating
5*10^-10/5*10^-10 which is interpreted as (5*10^-10/5)*10^-10, which indeed is 10^-20.

Radian mode does not work properly

-1E-13 is a very small number. When doing this kind of a problem you can regard 1E-13 as 0.

Remember that pi is an irrational number. It is only estimated on your calculator. I just played around with a TI-83 and found the following answers:

cos(pi/2) = 0
cos(2*pi + pi/2) = 0
cos(4*pi + pi/2) = 1E-13
cos(20*pi + pi/2) = -1E-13

As you know, that correct answer to each of these is 0. The calculator gives non-zero answers because some very small errors are accumulating. There is nothing wrong with your calculator.
